In Depth Understanding Of The Chemical Composition And Function 30crnimo8 Steel - China

30crnimo8 steel is an alloy structural steel widely used in manufacturing high-strength and high-toughness mechanical parts.

its chemical composition and the role of each element are as follows: ### the role of each element in 30crnimo8 steel

1 - **carbon (c)**: increases the hardness and strength of steel and promotes quenching hardening.

2 - **manganese (mn)**: improves the strength and toughness of steel, improves hardenability, and reduces brittleness.

3 - **silicon (si)**: enhances the strength and elasticity of steel while improving oxidation resistance.

4 - **chromium (cr)**: improves wear resistance and corrosion resistance, enhances quenching performance, and increases the hardness of steel.

5 - **nickel (ni)**: improves toughness and impact resistance, improves low-temperature performance, and reduces brittleness.

6 - **molybdenum (mo)**: improves high-temperature strength and wear resistance, improves hardening ability, and enhances hardenability.

7 - **phosphorus (p)**: excessive amounts will reduce toughness, so it is controlled at a low content.

8 - sulfur (s): excessive amount will reduce the plasticity and toughness of steel, so it also needs to be controlled at a low content.
